William Optics ZenithStar 73 Field Flattener with Adjustable Backfocus

Using this adjustable field flattener makes astrophotography with the William Optics 73 mm ZenithStar APO Refractor even better. This flattener contains a 63 mm opening on one end that threads into the telescope, and an M48x0.75 thread on the opposite end. Backfocus is adjustable up to 15 mm, and, once set, is held in place by a locking ring. Requires a camera specific M48 T-mount adapter for connecting to a DSLR camera.
